SPECIFICATION forming part of Letters Patent No. 448,226, dated March 17, 1891.

Application filed June 17,1390. Serial No. 355,779. (No model.)

To a whom (It mrty concern: I

Be it known that we, HENRY GOOSEN, RICIL ARD JOHN IIALY, and J AMES W. KENT, all citi- Zens of the United States, residing at Brook lyn, in the county of Kings, in the State of New York, have jointly in vented certain new and useful Improvements in Paint-Mills, of which the following is a specification.

Our invention relates to certain improvements in the details of a paint-mill having in View cheapness and simplicity of construction, more perfect cooling of the stones or grinding members by water or other cooling mixtures, the ready removal and renewal of the upper 1 or stationary stone, and the ready adjustment of the runner to accommodate it to uneven wear of the upper stone.

IVe will first fully describe our entire mill with reference to the accompanying drawings, and then point out in the claim the novel features thereof.

In said drawings, Figure I is a vertical sectional view of our improved paint-mill. Fig. II is a sectional plan taken on the line H II of Fig. I and omitting the driving mechanism. Fig. III is a sectional plan taken through one of the spindle-bearings.

The stationary frame 1. of the machine supports at top an annular stationary stone or grinding member 2 and the hopper 3, both of these members having flanges 4 5 projecting over the top of the frame and united thereto by bolts 6. IVhen united in this way, the stationary grinder is readily removable when worn out.

In the llange 5, and immediately over the annular grinder 2, is formed a chamber 7, which is annular except for a break at the point 8, where a diaphragm divides the chamber radially. By making the annular chamber in the flange of the hopper several advantages occur. 'lhe hopper being of metal or other moldable material, the chamber is more economically constructed, and the conducting capacity of the material covering the face of the grinding-stone greatly increases the cooling effect, as the contacting surfaces are large. Moreover, thelocation of the chamber in the hopper-flanges in addition to decreasing the cost of a grinding'stone obviates the necessity of changing or in any way affecting the water-chamber when the stone is removed, forin other constructions where the water-space is in the stone the trouble and expense of making water-joints is an incident 5 5 to the replacing of the stone.

9 10 are respectively inlet and outlet water-pipes connected with the chamber 7 on opposite sides of the diaphragm Sand supported on the exterior of the hopper, as shown. By this arrangement a constant stream of water may be kept flowing in the chamber 7, and the stone 2 may be kept cool effectually. The pipe 10 discharges the water into the funnel of a pipe 11, which projects through thetop and nearly to the bottom of the hollow runner or lower stone 12. From near the top of the runner a pipe 13 takes away the water as it rises above the level of the grinding-surfaces on the outer periphery of the runner and discharges it into an annular pan 14:, which is carried by cross-beams 15 of the stationary frame.

An outlet 10 is provided in the pan 14c for carrying away the waste water.

The runner 12 is supported 011 spindle 17,

stepped in a lever 18, which is hung at one end by means of link 19 from the cross-beam 20 of the stationaryframe, and has at the other end an adjusting-screw and wheel 21 supporting it from the same cross-beam.

The driving mechanism of the spindle may be of any preferred form. \Ve have shown fast and loose pulleys on a shaft 23 and bevelgearing 24 between the shaft 23 and the spindle 17. Such mechanism is convenient, as it can be readily removed on removing the top cover of the box of the shaft 23.

The spindle 17 is held in two brasses or bearings 25,each supported in one of the cross- 0 beams 15 20, and each split, as shown in Fig. III. These bearings rest by flanges 26 on their supporting cross-beams. They are sufficiently small in diameter to have a limited capacity for adjustment horizontally in the cylindrical 5 socket 27 provided for them in the crossbeams, and screws 28 pass through the walls of such socket and are made to engage with the bearings. In this manner the spindle may be adjusted to a perfectly vertical position, or Ioo slightly tilted therefrom, if necessary, to obtain an even bearing for the entire grindingsurface of the stones when one part wears more rapidly than another. As, owing to the 5 rotation of the runner with drip-pipe 13, the upper bearing 25 is somewhat inaccessible, we mount in the pan 14 a pipe 29, projecting through the walls of said pan and adapted to receive oil and convey it to the said bearing. I0 Having thus described our inventiom the following is what We claim as new therein and desire to secure by Letters Patent:

In a paint-111achine,the combination of a suitable frame having the upper flange, the I5 hopper having an annular flange extending outward and an annular Water chamber formed in the annular flange of the hopper, the upper grinding member corresponding to the opening in the hopper and having a flange extending outward .and in contact with the 20 hopper-flange, the lower grinding member having suitable water-space, the vertical post, on which the lower grinding member is mounted, and which has suitable connection with the driving-gear, the upper grinding member 25 and hopper being secured by means of bolts passed through their flanges and the flanges of the frame, and the machine being provided with suitable inlet and outlet pipes for water, substantially as set forth.
